The programmable sensors enable to measure of temperature and humidity in food, pharmaceuticals and raw material stores, museums, archives, galleries, meteorological stations etc. The measuring sensors are located in an external probe that is connected with a connection head of electronics by a cable. The probe of the sensor is placed to a measured space and cannot be disconnected from the connection head with electronic circuits. The connection head with the sensor electronic is designed for wall mounting. Easy mounting of the temperature sensor is ensured by the unique “S Head” design invented by SENSIT s.r.o.
Digital conception with microprocessor provides long-term stability of parameters, temperature compensation of the humidity sensing element and failure state signaling. The most up to date polymeric sensing element for humidity guarantees stability of indication and resistance to condensation water.
Two galvanically separated current signals 4 to 20 mA are available as output signals of the measured variables, the outputs are set by the producer as follows:
- The value on the output i1: relative humidity, range 4 to 20 mA is related to 0 to 100 % RH
- The value on the output i2: temperature, range 4 to 20 mA is related to -30 to 105 °C
A calibration sheet is included in the sensor price.
The sensors are designed to be operated in a chemically non-aggressive environment.
DECLARATION, CERTIFICATION, CALIBRATION
- EU Declaration of Conformity – in accordance with Act 22/1997 Coll. on technical requirements on products as amended.
- Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard, as amended) or in an Accredited laboratory.
